皇甫川流域柠条林地水分动态模拟——坡度、坡向、植被密度与土壤水分的关系
Description :
[中文摘要]：在皇甫川流域,随着林草覆盖度的增加,植被与水的矛盾日益突出,其中一个重要的问题就是植被密度与土壤水分之间的矛盾。土壤水分的降低影响了植被的生长,甚至导致了部分植被的死亡,因此对土壤水分与植被密度之间的关系进行研究非常重要,有助于合理造林密度的确定。在已有研究及实验观测的基础上,建立了柠条(Caragana intermedia)林地土壤水分动态模拟模型,模型考虑了主要的土壤、植物过程,包括土壤性状、降雨入渗、植物蒸腾、地表蒸发等;模拟了从1971至2000年,30年里各种立地条件(不同盖度、坡向和坡度)下的柠条林地土壤水分、蒸腾和蒸发等的日动态过程。通过比较不同立地...
